[Resolved] Special page for not registered users

How to set/create a page , that will show at http://siteadress.com/ (just after typing url) ONLY for not registered persons?

I have set that page: http://airsoftbook.com , but i don’t want to show the content of site (activities) for not registered users. I want to show there (in that place, right boxes are ok) a welcome message and some picture.
